That is, this plate extends from the west coast of North America to the middle of the Atlantic Ocean. 从“The top layer of the earth is called the earth’s crust”,可以推断出答案。反馈 收藏
About 98 per cent of the total crust of the earth is composed of eight elements like oxygen, silicon, aluminium, iron, calcium, sodium, potassium and magnesium, and the rest is constituted by titanium, hydrogen, phosphorous, manganese, sulphur, carbon, nickel and other elements. Show More ...
So when the volume of energy accumulated was too big to be supported by the earth crust, suddenly all that energy accumulated over the centuries was released in about one minute during the first earthquake." It is estimated that the Anatolia fault moves two centimeters each year,...
The troposphere, the bottommost layer of Earth’s atmosphere, is the densest of the five atmospheric layers and extends from ground level up to about 10 kilometers in altitude. This is the layer where humans live and breathe, as it contains the air we depend on for survival. The tropospher...
Earth is estimated to have formed 4.54 billion years ago from the solar nebula, along with the Sun and other planets.[10] The moon formed roughly 20 million years later. Initially molten, the outer layer of the planet cooled, resulting in the solid crust. Outgassing and volcanic activity pro...

has its own properties, composition, and characteristics that affects many of the key processes of our planet. They are, in order from the exterior to the interior – the crust, the mantle, the outer core, and the inner core. Let's take a look at them and see what they have going ...
Lava rocks are composed of high amounts of iron and magnesium elements (collectively referred to as the ferromagnesian group) as well as calcium. Due to their chemical composition, basalts are the most abundant rock type of the ocean floor and Earth's crust, and are the primary rock layer ...
